Ischemic stroke produces the highest adult disability. Despite successful recanalization, no-reflow, or the futile restoration of the cerebral perfusion after ischemia, is a major cause of brain lesion expansion. However, the vascular mechanism underlying this hypoperfusion is largely unknown, and no approach is available to actively promote optimal reperfusion to treat no-reflow.

Although cell-type specificity has been implicated in NVC, how active neural information is conveyed to the targeted arterioles in the brain remains poorly understood. Here, using two-photon focal optogenetics in the mouse cerebral cortex, we demonstrate that single glutamatergic axons dilate their innervating arterioles via synaptic-like transmission between neural-arteriolar smooth muscle cell junctions (NsMJs).

However, whether the vascular smooth muscle cell (VSMC) secretome regulates the connectivity of neural circuits remains unknown. Here, we show that conditioned medium from brain VSMC cultures enhances multiple neuronal functions, such as neuritogenesis, neuronal maturation, and survival, thereby improving circuit connectivity.

Therefore, quality inspection takes a key role in the pharmaceutical industry. Most of the previous solutions are based on machine vision, however, their performance is limited by the RGB sensor.

This study aimed to explore the role of PSD95 in (Ang-(1-7))-Mas-mediated cerebral ischaemia protection and its regulatory mechanism.
Methods: Oxygen-glucose deprivation (OGD) neuron and rat middle cerebral artery occlusion (MCAO) models were used as in vitro and in vivo models, respectively.
Platelets are derived from megakaryocytes and play an important role in blood coagulation. By using high throughput sequencing, we have found that the long non-coding RNA (lncRNA) nuclear paraspeckle assembly transcript 1 (NEAT1) is abundant in platelets (GEO ID: 200097348). However, little is known about its role in regulating megakaryocyte differentiation and platelet activity.

Methods: By 4/5-color multi-parameter flow cytometry (MFC, CD45/SSC gating) for detecting MRD at pre-(day-30) and post-transplant (day +30, +60, +100, 6 months, 9 months and 12 months), the investigators retrospectively analyzed the MRD levels and the prognosis of 90 high-risk patients. According to the MRD cutoff value of 0.
Objective: To evaluate preliminarily the significance of detecting the Wilms' tumor (WT1) gene level on monitoring minimal residual disease (MRD) and predicting the clinical outcome in patients of acute leukemia following hematopoietic stem cell transplantation (HSCT).
Methods: The mRNA expression levels of WT1 and house-keeping gene ABL were dynamically measured with Real-time quantitative reverse transcription polymerase chain reaction (RQ-RT-PCR) on 326 bone marrow samples from 63 post-HSCT patients in our hospital from December 2001 to September 2009. After comparing the WT1 levels of patients with different post-transplantation outcomes, the investigators used the receiver operating characteristic (ROC) curve to determine the WT1 threshold so as to predict their clinical relapses.
